In philosophy, as well as other fields, feminist reclamation has been the rediscovery of women thinkers, who have been neglected in traditional intellectual history, especially before the 1980s. Some of these women are considered philosophers only if philosophy is broadly construed. But others worked comprehensively on issues central to their field, influenced their peers, and have only recently been fully recognized for their achievements. A strong example of this category is Ruth Barcan Marcus.
